4.2.1
Connecting the inlet
• Connect the inlet to the muff <19>.
The inlet can optionally be mounted to one of the pre-scored
areas (see 2.4.1). Make sure that:
• The inlet is located above the level sensor for pump
switch-on. Otherwise backwater will occur in the inlet pipe.
Alternatively, the switching points must be adapted.
• Do not position the inlet in the direct vicinity of the level sensor
since the function of the sensor could be impaired by soiling
and the wastewater inflow.
• Use matching drill bit and all-round seal.
• Align the centre of the drill hole to the centre line of the pre-scoring area.
• Do not deburr the edges of the drill hole, this could lead to leaks.
4.2.2
Connecting the venting pipe
• Connect the venting pipe to the venting connection <18>
(according to DIN EN 12056-4).
Connections and clamps should have sound-reducing
properties.
